Google works exhausting to give protection to your Android gadget: regardless of the place your apps come from. Continuing the development from earlier years, Android units that simplest obtain apps from Google Play are nine occasions much less more likely to get a PHA than units that obtain apps from different resources.

Devices with Potentially Harmful Applications put in through Android model

Newer variations of Android are much less suffering from PHAs. We characteristic this to many elements, comparable to persevered platform and API hardening, ongoing safety updates and app safety and developer coaching to cut back apps’ get right of entry to to delicate knowledge. In specific, more recent Android variations—comparable to Nougat, Oreo, and Pie—are extra resilient to privilege escalation assaults that had prior to now allowed PHAs to realize endurance on units and offer protection to themselves towards removing makes an attempt.
